Title: Pet toy product with integral treats receiving receptacles
Inventor: MARKHAM JOSEPH P
IPC: A01K11/00
Filed: 1997-06-06
Abstract: A pet toy product (T) is provided for holding one or more animal treats (18) wherein the toy has a body member having an outer surface with one or more recesses (13, 14, 16) for removable holding one or more animal treats. The recesses (13, 14, 16) may be of varying depth so that the treats (18) in the deeper recesses (16) are more difficult for the animal to extract than are the treats in the shallower recesses (13). The recesses (13, 14, 16) may be circular, triangular, irregular, in the form of a groove (20, 22, 24) or any other suitable configuration. The outer surface of the toy may be raised to accommodate the recesses (13, 14, 16, 20, 22, 24) or the recesses may extend into the surface. Finally, the pet toy may have a recess forming an opening (54) which extends through the side wall of the pet toy product for receiving a treat (18). With the structure recited, the pet owner can replenish the treats as often as necessary to maintian the pet's interest in the toy.  Different treats can be provided with different nutritional values and tastes.  Because some treats will be more difficult for the animal to remove than others, the animal can be kept occupied for several hours before the treats need to be replaced again. The treats (18) may be held in the recesses (13, 14, 16, 20, 22, 24, 54) by friction, adhesive or adhesion.

Inventor: NAGEL THOMAS O
IPC: G09F3/20
Filed: 1999-02-26
Abstract: A sign holder device for mounting on the projecting lower margin of a display shelf ticket molding or label holder. The device is of injection molded construction having spaced apart side walls joined by top and bottom walls. A pair of mounting clips extend rearwardly and then upwardly from the bottom wall in general alignment with the respective through openings. Resilient plastic tabs, extending forwardly from the mounting clips, allow the device to be mounted on a variety of label holder configurations, where the label holders have a downwardly projecting lower edge margin to be received in the mounting clip. Abutment clips project rearwardly from the sidewalls toward the mounting clips and define locking recesses adjacent the bottom of the sign holder. This enables the sign holder to be applied over the lower edge of a flanged ticket molding and to be lockingly retained thereon by engagement of the lower flange within the locking recess.

Title: Motor and end frame therefor for machine or pump applications and method of assembling same
Inventor: LIN CHIH M
IPC: H02K5/15
Filed: 1999-03-22
Abstract: An electric motor for a machine or pump assembly and method of assembling the motor and the pump assembly. The machine or pump assembly includes an electric motor having a housing, an end frame and a bolt extending through the housing and the end frame to secure the housing and the end frame together. The end frame includes a through-bore having an inner diameter.  The bolt has a major diameter that is greater than the inner diameter of the through-bore so that when the bolt is turned into the through-bore, the bolt creates threads in the through-bore of the end frame. When the electric motor is placed next to the housing, the bolt is turned to strip the threads in the through-bore and screw the bolt into the housing of the pump apparatus.
Patent CA-2267010-A1 (CA)
Inventor: DOMESLE RAINER
IPC: B01D53/94
Filed: 1999-03-26
Abstract: The invention relates to a process for operating an exhaust gas treatment unit for an internal combustion engine which is operated with lean normalised air/fuel ratios over most of the operating period. The exhaust gas treatment unit contains a nitrogen oxides storage catalyst with an activity window .DELTA.T NOX for the storage of nitrogen oxides at normalised air/fuel ratios of greater than 1 and release of the nitrogen oxides at normalised air/fuel ratios of less than or equal to 1 and a sulfur trap, located upstream of the nitrogen oxides storage catalyst, with a sulfur desorption temperature T S,DeSOx above which the sulfates stored on the sulfur trap are decomposed at normalised air/fuel ratios of less than or equal to 1.      The nitrogen oxides contained in the exhaust gas are stored on the nitrogen oxides storage catalyst and the sulfur oxides are stored on the sulfur trap at normalised air/fuel ratios greater than 1 and exhaust gas temperatures T K within the activity window T NOX, wherein at the same time the exhaust gas temperature just upstream of the sulfur trap is lower than its sulfur desorption temperature T S,DeSOx. By cyclic lowering of the normalised air/fuel ratio in the exhaust gas to less than 1 the stored nitrogen oxides are released again from the storage catalyst. (Conclusion of a storage cycle). After each predetermined number N1 of nitrogen oxides storage cycles, sulfur is removed from the sulfur trap. This takes place by raising the exhaust gas temperature just upstream of the sulfur trap to above its sulfur desorption temperature T S,DeSOx and also lowering the normalised air/fuel ratio in the exhaust gas to less than 1.

Title: Low nox flat flame burner
Inventor: SHANNON ROBERT A
IPC: F23D14/24
Filed: 1998-03-19
Abstract: A flat flame burner (30) is disclosed having flow passages (32, 42) for admitting fuel and air to a burner tile. A structure (34) for producing a rotational flow cooperates with a divergent burner tile (36) in order to produce a radially-divergent flame with a very small axial component and a high degree of entrainment of inert combustion products in a furnace. A portion of the fuel is injected into the entrained furnace products, in order to suppress the rate of combustion, so as to produce an ultra low NOx flat flame burner. The present invention also permits greater versatility and operability over previous flat flame burners.
